Please helpppp

Okay so I just went through a lot down there, found out my bf of a years ex gave him chlamydia so I’ve had it untreated for about a year, that turned into PID also, thought I had a miscarriage because a big chunk of like, white veiny tissue stuff came out on my tampon during my cycle (still not 100% sure what it was), I had a UTI and my birth control (depo) was giving me serious complications on top of all this too. I went and got the chlamydia taken care of and my birth control is over now. This all happened about two months ago and I haven’t had a period till a few days ago. But it’s more spotting and it’s a really really dark brown. And I’ve been having severe cramps like I had from the chlamydia. I’m scared about what could be going on like if I haven’t gotten rid of the chlamydia or if all that stuff just messed me up bad. Please let me know what you guys think it may be!?!
